6.5 LUBRICATION
6.5.1 GENERAL REMARKS
LUBRICANTS
For friction bearings “steel-on-steel” and roller bearings lubricants and oils based on MoS
2
are recommended. For bearings containing brass, bronze or copper components, only MoS2-free
lubricants and oils shall be used.
ENGINE
For lubrication of the engine, the instructions in the »Maintenance Manual (Line Maintenance)
for ROTAX Engine Type 914 Series«, section »12-20-00«, (Annex E) and the relevant Service
Information (SB), Service Information (SI) and Service Letter (SL) must be observed.
BEARINGS OF CONTROL SYSTEM AND CONTROL SURFACES
The control system bearings in the fuselage and in the wings are provided with permanent greasing
and do not require any service for a long period.
The control surface bearings (except rudder bearings) are coated and normally greasing is not
required. However, greasing may be necessary in aggressive environmental conditions when bolts
show first signs of corrosion. In this case use MoS2-free grease.
The rudder hinges must be greased depending on the degree of exposure to contamination
(especially the lower hinge).
CONNECTION OF THE PROPELLER EXTENSION SHAFT TO THE CLUTCH ON THE ENGINE SIDE
(SPLINED JOINT)
Shafts with hard film coating. Commercially available Teflon spray or
non-acid grease can be used for lubrication
if there is only minor damage to the hard
film coating.
CANOPY LOCKING
Always keep well-greased. Use MoS
2
-free lubricant, since the rod bearing within the canopy
frame is made of brass.
